Industrial Casters. Engineered for Spec.
Chair and furniture casters with 7/16" x 7/8" grip ring stems are the universal standard for office seating, dining chairs, bar stools, and residential furniture. These casters snap securely into pre-formed sockets and are semi-permanent (removable with a tool if needed). Smooth, quiet rolling in rubber, polyurethane, or TPR wheels protects hardwood and tile floors. Available with and without brakes for stationary capability.
The 7/16" x 7/8" grip ring became the furniture industry standard decades ago because it provides optimal security, easy installation, and universal compatibility. The tapered stem fits snugly into furniture leg sockets, and the spring-loaded grip ring holds it without visible fasteners. Almost every furniture manufacturer worldwide designed chairs, stools, and seating around this standard socket size.
Grip ring stem casters are standard on office chairs (executive, task, gaming), dining chairs and bar stools, residential seating (recliners, sofas on wheels), kitchen islands and dining tables, and commercial lounge seating. If your furniture has a socket in the leg and you need replacement casters, 7/16" x 7/8" grip ring is almost certainly the right choice.
